5.6.18
5.6.18.1
These register bit values represent the pending IRQs for interrupt vector numbers 49 through 63.
Ascending IRQ numbers correspond to ascending bit locations.
5.6.19
5.6.19.1
This read-only bit reflects the state of the interrupt to the 56800E core.
5.6.19.2
These read-only bits reflect the state of the new interrupt priority level bits being presented to the 56800E
core. These bits indicate the priority level needed for a new IRQ to interrupt the current interrupt being
sent to the 56800E core. This field is only updated when the 56800E core jumps to a new interrupt service
routine.

0 = IRQ pending for this vector number
1 = No IRQ pending for this vector number
0 = No interrupt is being sent to the 56800E core
1 = An interrupt is being sent to the 56800E core
00 = Required nested exception priority levels are 0, 1, 2, or 3
01 = Required nested exception priority levels are 1, 2, or 3
10 = Required nested exception priority levels are 2 or 3
11 = Required nested exception priority level is 3
